How to Shutdown Netapp Cluster Mode Storage System with
Multi-Node Cluster (6 nodes cluster with ontap version 9.1P14
with model FAS8200, AFF8040 & AFF8020)
[if any command is not executing then you need to use the advance mode to execute them
and sometimes you need to type the command instead of simple copy and paste]
Action Items for powering down of Netapp SAN-:
 Take the backup of the NetApp configurations files for the future reference.
 Trigger the ASUP, for the starting of the maintenance activity.
 Shutdown all the connected CIFS/NFS clients and hosts that have FCP or iSCSI-based
LUNs. (All the host machine if you have a plan for Data Center maintenance or power
down activity)
 Shutdown the controllers first and wait for 1-2 mins.
 Shutdown all the disk-shelves one by one, by removing the power cords from the
respective shelves.
 Shutdown the network switches (if you have a plan to shut-down your Data Center)
1.Pre-checks
As a part of pre-checks,you can take the couple of commands out put into your notepad for the
future reference ifsomethingmissmatched after the poweringup the Netapp cluster.
 network interface show
 vserver show
 volumeshow
 system node show
 lunshow
 igroupshow -vserver *
 iscsi show
 iscsi security show
 iscsi sessionshow
 storage aggregate show
 storage diskshow
 storage shelfshow

2. Take Configuration Backup by executing the below command-:
Note- You needswitchto advanced mode and execute the belowcommand to take the configuration
backup as belowis the one example,the same way you needto take the backup for all the nodes.

3
Live Example-:
clus-prod-1::*> set-privilege advanced
Warning:These advancedcommands are potentiallydangerous;use them onlywhen directedto do
so by NetApp
personnel.
Do you want to continue?{y|n}: y
Syntax-:
#systemconfigurationbackupcreate -node <node name> -backup-type cluster -
backup-name <Name of the backup file>
clus-prod-1::*>systemconfigurationbackup create -node clus-prod-1n1-backup-type cluster -backup-
name Backup_Before_shutdown_clus-prod-1n1
[Job 77985] Job is queued:ClusterBackup OnDemand Job.
To see the job status as below-:
Syntax-
#Job show-id<job ID>
Live example-:
clus-prod-1::*>jobshow -id77985
Owning
Job ID Name Vserver Node State
------ ------------------------------ -------------- ----------
77985 CLUSTER BACKUP ONDEMAND
clus-prod-1 clus-prod-1n1 Running
Description:ClusterBackup Job
Now you can take the cluster configurationbackupfor all the nodes by
executing the commands as below.

4
To check the backup is taken or not by executing the belowcommand-:
clus-prod-1::*>systemconfigurationbackup show
3. Trigger the Autosupport, that you are doing some maintenance
activity so Netapp support can be aware of your activity.
clus-prod-1::>autosupport invoke -node * -type test -message “Power_down_Activity_started”
Note- * in the above command is for all the nodesASUP is triggering.
4. shut down all the connected CIFS and NFS clients. (If you wanted to
shutdown for the entire data center then do shutdown all the
connected CIFS and NFS clients)
If only needto shut down the Netappstorage system, thenexecutethe below
command-:
clus-prod-1::>cifssessionclose

5
clus-prod-1::>cifsstop -vserver*
clus-prod-1::>nfs stop -vserver*
Note – In above commands * representsfor all the Vservesin the storage system.
5.If your storage system is serving the SAN (FCP and ISCIS) LUNs, then
shutdown all the connected hosts before shutting down the storage
system.
6.Stop Vservers execute the below command-:
clus-prod-1::>vserver stop -vserver* -foregroundtrue
Note- It will show you the message of stoppingthe Vservers,ifyou will use the command -background
then it will be not visible inthe console.
Live example snapshot as below-:
clus-prod-1::>vserver show -fieldsvserver
Note- onlydata vserversare goingto stop, so if some vserveris not stopping thenplease ignore them
as they are offline vserveror clustervserver.
7. Identify Primary and Secondary Nodes
clus-prod-1::*> clusterring show

6
Note- This command will be executedin advancedmode and we can see the one node will be the
master and others will be the secondary nodes.
Live example-:Small portion of the snapshot as below.
Note-Nowyouhave identifiedwhichone isMaster and whichnodes are secondary.
Note-Checkfewthingsifyou wanted to rebootthe clusternodes but it isnot requiredto shutdown
the clusteras below.
clus-prod-1::> cf status

Note- Inabove the command output of “storage aggregate show -fields ha-
policy”you can have the aggregate status informationoncluster failover (CFO)
and storage failover (SFO). If you do manual cluster failover thenCFO
aggregates will be migrating fromnode to takeover node.
SFO = Storage Failover
CFO = ClusterFailover
RDB = ReplicatedDatabase
8.Disable Failover

nodes’takeoveror givebackprocess.
if you have two nodesthendisable HA more than two nodesdisable failover

clus-prod-1::> storage failovermodify-node clus-prod-1n*-enabledfalse
HALT Each Node in NetappClusterone by one but needto halt the secondary nodesfirst then the last
one would be the primary node.
To halt each node,loginto any one of the SP/RLM IP address thenhalt othernodes from master node.
Rememberto halt secondary nodesfirst. Ring show command will give more detailson node roles
which we have already executedthe command and taken the output.

clus-prod-1::>halt -node clus-prod-1n6-inhibit-takeovertrue -ignore-quorum-warningstrue -skip-lif-
migration-before-shutdowntrue -reason "Maintenance Activityplanned"

11
Action Items for powering up of Netapp SAN-:
 Power up ofall the network switches.(Incase of Data Centerpower up/down activity)
 Power up ofall the disk-shelves,thenwait5 to 10Mins, ifall looks good thenjump to the next
step.
 Power up ofall the controllers.
 Logging into the Netapp and needto do the post check validation.
Note-Like execute all the commands which we have executedbefore shutdownofthe Netapp
clusterand enable the cluster failoverby executingthe belowcommand.
 clus-prod-1::>storage failovermodify-node clus-prod-1n* -enabledtrue
 Trigger the ASUPas maintenance activityis completed
